I'd listen to Barry on this. He has some massive wheels.
Personally , my legs grow doing this kind of workout.
Squats: 5 x 5 (heavy)
Leg Press: 4 x 12r-15eps (1-2 minutes rest)
Lunges: 4 sets of 8 lunges each side with heavy weight.
Leg extension superset with ham curls: 4 x 15reps (1-2 minutes of rest).
That's only 17 sets of exercises for me, but I push myself pretty hard on leg days.
Barry is a beast though, so listen to him.
